, is necessary or desirableto provide means bottom of the car of auniversal wheel or pulley 36, wh ch guide is shown in Figures forholding the wheel in a substantially vertical plane, while' permittingit to swing in a horizontal plane. One form of such 6 and 7 in which abar 29 is pivoted at 30 to a bracket 31 secured to the truck frame 11.Two wheels or rollers 32 are carried by the bar 29 and en. gage withtheopposite sides of the rim 26. These wheels or. rollers tend to hold thepulley upright while permitting it to swing in a horizontal direction asindicate-d by the dotted lines in Figure 7. 7

The generator 33 is hinged at 34 to the 35 and is driven by means issimilar in construction to the pulley 14. However, in this instance therim 37 is not split. The hub 38 is connected to the rim by bent spokes39 and is split in the'plane of the wheel, the parts being held togetheri by bolts 40. This hub has a bearing or tusprings 49 are bularprojection 41, which is secured to a shaft- 42 of the generator by meansof set screws 43 or in any other suitable manner.

A. bracket 44 is-secured to the generator and has a bar 45 pivotedthereto at 46. This bar is provided with guide rollers 47 to enwith therim 37 for guiding the pulley. A drivin belt 48 passes around thepulleys 14 and 36. One or more adjustable arranged to pull on thegenerator 33 so as to keep the belt tightened at all times. V

"In the modification shown in Figure 9,

the pulley 36 is provided with two guide rollers 50, which engage withthe same side of the wheel, one being at the top and the other at-thebottom. These rollers are carried b arms or bars 51, which are pivotedat 52 to brackets 53 secured to the'generator, It will also be notedthat a similar modification'may be utilized with the pulley 14,

, although "I prefer the arrangement above described. 7

With this approved form of transmission, the pulleys on the axle andgenerator will always stand in the same vertical plane or be inalignment'withreach other and with V the belt. i Consequentlya properdriving relation is always maintained and there will be little or nochance of the belts being It will 'also'be noted that the device can bereadily taken off, of one car and applied to another, or new partssupplied which fit va rious sizes of axles. l

7 It will also benoted that various changes may be made in the detailsof construction and arrangement of the parts in order to apply thetransmission to various types of cars-andtherefore I do not wish to belimited 'to the particular arrangement herein ing sockets formedintegrally therewith,

bent spokes engaging with said sockets, a split hub for receiving theinner ends of the spokes and means for fastening the hub to a shaft of arailway car. 7
